Yes. I think that something that should be done, and sooner rather than later, is changing more options from 'default n' (the default when not spelled out) to 'default y' as with the change from board.h to Kconfig there is much less pain in turning off default values. Things like 'ums' are really handy and unlike DFU/fastboot don't require additional configuration. So, I should go and fire off a patch for this one quickly at least. -- Tom
